Has this happened to anyone else or am I just on an unlucky streak? |
There are multiple DME failures on the forum. My personal opinion is that yes, piggybacks play a role in DME failures. I would like to see one person with DME failure who is not running a piggyback or has not ran it at some point in time. There are so many things that can happen: impedance mismatch (leading to high current through some of the output transistors), short circuits, statical electricity, etc.
